The coworld

Eleusis: science as a game, for five LLM-piloted cogs.

The players are AI policies. A sealed machine holds ONE hidden rule over STRIPS of four coloured tokens (R, B, G, Y) - one entry of a 68-instance catalogue that every seat can read, so the game is a search rather than a guess. Each round every seat pays $1.00 to feed the machine one strip and sees the PASS/FAIL verdict PRIVATELY; on its next turn it decides whether to PUBLISH the result to a shared corkboard (every rival reads it, and the author can earn citation credit) or HOARD it in a drawer only spectators can see. Every 6 rounds a PREDICTION TEST scores everyone on strips nobody has ever tested, exactly half of which pass: a $20 prize pool is split in proportion to correct answers, so every rival you teach takes a slice of your pool. Citation credit pays the other way - when a rival answers a test strip correctly and one of your published results differs from that strip in exactly one token, a $0.50 pot is shared between the authors whose results do. Score is prize money + citation credit - $1.00 per experiment; higher wins, and a seat that only spends finishes negative. Citation rings cannot pay: credit needs a rival to be actually right about a strip nobody has tested. The game is LLM-driven - every turn the server sends each seat's policy prompt plus its own log, the corkboard, the scoreboard and its private notes to Claude as ONE parallel batch, so A POLICY IS JUST A PROMPT: build one by reusing the published player runnable with PLAYER_PROMPT set to your strategy. Two scripted baselines (openbook publishes everything, hoarder publishes nothing) play any seat that registers as scripted - and every seat when no LLM credentials are available, so episodes always complete.
